On to more progress. Began by soaking the fasteners the other day and re-soaked before starting this evening. Chased the exposed threads of all manifold studs with a 3/8 - 24 die. The nuts were still brass (to my utter surprise) and came off with relative ease. One stud backed out with no damage. The exhaust flange bolts came apart with ease also. One interesting note (And Flackmaster mentioned this while he, Big Kev, and I were visiting Egge in January) there appears to be no intake to exhaust heat box gasket. The bolts look original and undisturbed and there seems to be no leaks! Heat damper seems to work freely and properly, so I might leave well enough alone.
Cleaned up the manifold block surface and moved on to cylinder head removal. Pulled spark plugs and found all 8 to be uniform fluffy brown. How fortunate I thought. Soaked the head bolts and soaked studs while removing other odds and ends. Ate dinner and went out to fill my truck. When I returned I tapped the side of the cylinder head with a large shot filled dead blow hammer and the head soon changed sounds as it released from the head gasket. The head came off with ease to revel a terrific looking top end. Inspection of the bores and valves showed no evidence of trouble. The valve faces are clean with no cupping or pitting, seats in excellent shape and valve margins are nice and thick.
Remembered that Kev's car had an issue with loose #7 exhaust and my car was actually collapsed #6 exhaust. Good thing I read back through this thread to refresh my memory. No matter, I would have double checked and realized this I suppose.
Tomorrow I will attempt to remove the hydraulic lash adjuster body from the body of the tappet. Might involve designing and machining some special collar clamp tools to hold the lifter and tappet bodies to avoid damage if they are stuck together. I remember JD mentioned this condition in his thread.
